The Center for Expanded Data Annotation and Retrieval (CEDAR), one of the eleven BD2K centers of excellence, is working to make it easier for biomedical investigators to author metadata that are more complete and more comprehensive than is possible with manual methods.  CEDAR makes it easy for scientists to use standard metadata templates and standard terms from well-recognized ontologies to fill in the templates.  A database of previously entered metadata enables the system to use predictive data entry to guide its users in their work to author metadata.  CEDAR should help to make online biomedical datasets more “FAIR,” while facilitating the information-retrieval work performed by BioCADDIE by ensuring higher-quality metadata.


Dr. Musen is Professor of Biomedical Informatics and of Biomedical Data Science at Stanford University, where he is Director of the Stanford Center for Biomedical Informatics Research.  Dr. Musen conducts research related to intelligent systems, reusable ontologies, metadata for publication of scientific data sets, and biomedical decision support.  His group developed Protégé, the world’s most widely used technology for building and managing terminologies and ontologies. He is principal investigator of the National Center for Biomedical Ontology, one of the original National Centers for Biomedical Computing created by the U.S. National Institutes of Heath (NIH).  He is principal investigator of the Center for Expanded Data Annotation and Retrieval (CEDAR).  CEDAR is a center of excellence supported by the NIH Big Data to Knowledge Initiative, with the goal of developing new technology to ease the authoring and management of biomedical experimental metadata.  Dr. Musen directs the World Health Organization Collaborating Center for Classification, Terminology, and Standards at Stanford University, which has developed much of the information infrastructure for the authoring and management of the 11th edition of the International Classification of Diseases (ICD-11). 

Dr. Musen was the recipient of the Donald A. B. Lindberg Award for Innovation in Informatics from the American Medical Informatics Association in 2006.  He has been elected to the American College of Medical Informatics, the Association of American Physicians, and the National Academy of Medicine.  He is founding co-editor-in-chief of the journal Applied Ontology.
